Subpicosecond-time-domain reflectometry
Optics Letters, 1981We demonstrate a new method of optical time-domain reflectometry using subpicosecond pulses and nonlinear detection. The high-spatial-resolution ( approximately 15-microm) temporal resolution and sensitivity put new limits on the size and nature of defects that can be detected, localized, and analyzed in optical fibers.

Simulation of Time-Domain Reflectometry
Applied Mechanics and Materials, 2017 This paper introduces a simulation work of Time-Domain Reflectometry (TDR). The TDR analysis begins with the propagation of a step or impulse of energy into a system and the subsequent observation of the energy reflected by the system. By analyzing the magnitude, duration and shape of the reflected waveform, the nature of the impedance variation in the
